Installation and wiring

2.1 Installation precautions

| Make sure the device has been powered off before installation.
---|---
Note| There are three expansion module interfaces on the control box (expansion slot 1, expansion slot 2, expansion slot 3). You can use expansion slot 1 or expansion slot 2 according to the actual wiring.
It is recommended to install the I/O expansion module at expansion slot 2.

Required tools: Phillips screwdriver PH1, straight screwdriver SL3
Table 2-1 Screw torque requirements

2.2 Dimensions
The dimensions of the I/O expansion module is 73.5×103×36.1mm (WHD).
Figure 2-1 Product dimensions (unit: mm)

2.3 Installation instructions
It is recommended to place the I/O expansion module at expansion slot 1 of the control box. The following is an example of the installation at slot 1.
Step 1 Place the module in the corresponding position of the control box expansion slot 2, align it with the slot, and then buckle it together.
Step 2 Align the expansion module positioning hole with the positioning stud.
Step 3 Fix with a M3 screw. The installation is complete.

Note:

• The expansion module and control box are electrically connected through slots. Please install them in place.
• To ensure the reliable operation of the expansion module and meet EMC requirements, please tighten the screws according to the recommended torque for reliable grounding.

2.4 Disassembly instructions
You can disassembly the module by reversing the order of steps described in section 2.3 Installation instructions.
Step 1 Disconnect all power supplies and disassemble all cables connected to the expansion module.
Step 2 Use a Phillips screwdriver PH1 to remove the grounding screws of the module.
Step 3 Lift the module out of the control box positioning stud and pull it out to a suitable position. Disassembly is complete.

2.6 Wiring precautions
Note:

• Analog input should not exceed the range: 0–10V, 0–20mA.
• Analog input/output type selection: The jumper selection signal (voltage or current) must be consistent with the input method of the user interface.
• As shown in Figure 2-4, J1/J2 are used to select the analog input signal type and J3/J4 are used to select the analog output signal type. For voltage signal input/output, short circuit the two adjacent terminals at the upper part. For current signal input/output, short circuit the two adjacent terminals at the lower part.
